Abstract

The composting plant for refuse and sludge, according to the present invention, has an inclined base and mixer screws which do not have air induction channels. They are placed on axes which are perpendicular to said base and which rotate around and move along said axes, respectively during mixing and homogenization of the material to be treated and during return and travel starting. These screws are carried on a mobile bridge whose carrying beam is parallel to the generally inclined bottom of the composting reactor and has the relative mobile supports for rolling resting on a concrete bed in direct contact with the ground. The air required for the treatment of the material is sucked from the bottom of the reactor through channels cut into said bottom and covered by means of protection to avoid blockage caused by deposits of composting material which may infiltrate. The same are removed by periodic washing with water, pumped inside the channels by means of special devices.
